FEATURES

LT6656

1µA Precision Series

Voltage Reference

DESCRIPTION

The LT

6656 is a tiny precision voltage reference that

draws less than 1µA of supply current and can operate

with a supply voltage within 10mV of the output voltage.

The LT6656 offers an initial accuracy of 0.05% and tem-

perature drift of 10ppm/°C. The combined low power and

precision characteristics are ideal for portable and battery

powered instrumentation.

The LT6656 can supply up to 5mA of output drive with

65ppm/mA of load regulation, allowing it to be used as

the supply voltage and the reference input to a low power

ADC. The LT6656 can accept a supply voltage up to 18V

and withstand the reversal of the input connections.

The LT6656 output is stable with 1µF or larger output

capacitance and operates with a wide range of output

capacitor ESR.

This reference is fully specified for operation from –40°C

to 85°C, and is functional over the extreme temperature

range of –55°C to 125°C. Low hysteresis and a consistent

temperature drift are obtained through advanced design,

processing and packaging techniques.

The LT6656 is offered in the 6-lead SOT-23 and (2mm

2mm) DFN Packages.
